Really sad to hear this. I spoke to Don when I was selling my BBB. He was a unique character. We hit it off n the phone for over 3+ hours! Don shared an abbreviated version of his life story, family business, and eccentric pinball collecting. He even insisted I google earth his home address in Beverly Hills so he could point out his house - then zillow - so he could give me a virtual tour. We didn't end up working out a deal, but what a charismatic guy. Offered next I'm in town to swing by play pinball, see the area and hang out. Never happened, my loss.
Rest in peace Don. Thanks Rarehero for letting us know of his passing.
